What are business expenses?

Business expenses are the costs you pay to keep your company running day to day. They include spending on inventory, supplies, insurance, rent, utilities, and professional services. When you subtract expenses from income, you get your profit, which is the amount you pay taxes on.

Why track business expenses?

Tracking expenses gives you control over your finances and helps your business run more efficiently. These are the main reasons to make it a priority.

Maintain accurate financial records

Accurate records protect your business during audits and help you meet compliance requirements. When every expense is documented, you can prove your deductions and avoid penalties.

Track cash flow and manage your budget

Expense tracking shows you exactly where your money goes. Seeing this clearly helps you spot overspending, plan for upcoming costs, and keep cash flow healthy.

The pressure to stay on top of cash flow is real. According to Xero Small Business Insights, US small businesses averaged only 2.4% sales growth in 2025, roughly half the long-term average of 5.5%. That's why keeping a tight grip on your spending matters more than ever.

Maximize tax deductions

Every legitimate expense you track reduces your taxable income, keeping more money in your business. Proper tracking ensures you claim everything you're entitled to.

Make better business decisions

Clear expense data helps you identify which costs deliver value and which ones you can cut. Use this information to set prices, plan growth, and become more profitable.

What are tax deductible expenses?

Tax deductible expenses are business costs the IRS allows you to subtract from your taxable income. To qualify, an expense must be both ordinary (common in your industry) and necessary (helpful for running your business).

Common deductible expenses include:

• Office rent and utilities: monthly payments for your workspace
• Business supplies: equipment, software, and materials you use daily
• Professional services: fees paid to accountants, lawyers, and consultants
• Travel costs: transportation, lodging, and meals for business trips
• Marketing expenses: advertising, website hosting, and promotional materials

For product-based businesses, the cost of goods sold (COGS), the direct costs of producing or purchasing the products you sell, is also fully deductible. Check the IRS Tax Guide for Small Business for more details.

Some expenses have limits. For example, business meals are typically 50% deductible, and employer-provided on-site meals are fully non-deductible as of 2026. Vehicle expenses require mileage tracking. Check the IRS website for current rules or speak to a tax professional about your specific situation.

The IRS has replaced Publication 535 with a new guide to business expense resources.

What are non-deductible expenses?

Non-deductible expenses are costs you can't subtract from your taxable income, even if they're related to your business. Knowing what doesn't qualify helps you avoid claiming ineligible deductions and keeps you on the right side of IRS rules.

Common non-deductible expenses include:

• Personal meals and entertainment: meals that aren't directly tied to a business meeting or travel don't qualify, and client entertainment costs have been fully non-deductible since the 2017 Tax Cuts and Jobs Act (TCJA)
• Customer gifts above $25: the IRS caps the deduction for business gifts at $25 per recipient per year; anything over that limit isn't deductible
• Personal expenses: costs like personal clothing, commuting to your regular workplace, and personal phone plans can't be written off, even if you occasionally use them for work
• Political contributions and lobbying: donations to political campaigns or lobbying activities are never deductible
• Fines and penalties: government-imposed fines, such as parking tickets or regulatory penalties, aren't deductible

If you're unsure whether a cost qualifies, check the IRS guide to business expense resources or consult a tax professional. Keeping non-deductible expenses separate in your bookkeeping records saves time at tax season and reduces audit risk.

Types of business expenses to track

Organizing expenses into categories makes tracking easier and helps you spot trends. Here are the main types most small businesses need to monitor.

• Operating expenses: rent, utilities, insurance, and other costs to keep your business running
• Office supplies and equipment: computers, furniture, software subscriptions, and everyday supplies
• Travel and transportation: flights, hotels, mileage, parking, and public transit for business purposes
• Marketing and advertising: website costs, social media ads, print materials, and promotional events
• Professional services: payments to accountants, lawyers, consultants, and contractors, which may trigger reporting requirements for payments totaling $2,000 or more per year (increased from $600 as of 2026)
• Employee costs: wages, benefits, payroll taxes, and training expenses
• Inventory, materials, and cost of goods sold (COGS): products you buy to resell, raw materials for production, and the direct costs of making what you sell
• Accrued expenses: costs you've incurred but haven't paid yet, such as wages owed, taxes payable, and utility bills that span billing periods

Track each category separately so you can see where your money goes and identify opportunities to reduce costs. For items that don't fit neatly into 1 category, group them under miscellaneous expenses and review regularly to see if a new category makes sense.

How to budget for business expenses

Budgeting for business expenses means setting spending limits by category before each month begins, then comparing actual spending to those limits as you go. It turns expense tracking from a backward-looking record into a forward-looking control.

Careful budgeting is especially important when incoming payments are unpredictable. Xero Small Business Insights data shows US small businesses waited an average of 27.9 days to be paid in late 2025, with payments arriving 7.8 days past the due date. When cash is arriving nearly a month after you invoice, planning your outgoing expenses in advance keeps you from overspending before revenue lands.

To build an expense budget:

1. Review at least 3 months of past spending to set realistic targets for each category.
2. Allocate limits for your biggest cost areas, such as rent, payroll, marketing, and supplies.
3. Compare actual spending to your budget at the end of each month and note where you went over or under.
4. Adjust your targets each quarter as revenue, costs, or business priorities change.

Accounting software simplifies this by pulling in real transactions and surfacing variances automatically, so you can spot overspending before it becomes a problem.

Methods to track business expenses

The right tracking method depends on your business size, budget, and how many expenses you handle. Here are your main options.

Manual tracking

Manual tracking means recording expenses by hand in a notebook or cash book. This approach works for businesses with very few transactions.

• Best for: solopreneurs with minimal expenses
• Pros: no cost, simple to start
• Cons: time-consuming, prone to errors, hard to scale

Spreadsheet tracking

Spreadsheet tracking uses tools like Excel or Google Sheets to log and categorize expenses. Many business owners start here before moving to dedicated software.

• Best for: small businesses with moderate transaction volume
• Pros: low cost, customizable, familiar interface
• Cons: requires manual entry, no automation, limited reporting

Expense tracking software

Expense tracking software automates data entry, categorization, and reporting. Tools like Xero connect to your bank accounts and capture expenses in real time.

• Best for: growing businesses that want to save time and reduce errors
• Pros: automatic bank feeds, receipt capture, built-in reporting, integrates with accounting
• Cons: monthly subscription cost

For most small businesses, software pays for itself through time savings and fewer missed deductions.

Step-by-step: how to track business expenses

Here's how to set up an expense tracking system that keeps your finances organized, step by step.

1. Separate business and personal expenses

Open a dedicated business bank account and credit card. This makes tracking simpler and keeps your records clean for tax time. For example, if you spend $200 on office supplies using a personal card, you'll need to sort that transaction out later. A dedicated business card eliminates that problem.

2. Choose your tracking method

Decide whether you'll use manual records, spreadsheets, or software based on your transaction volume and budget. If you process more than 20 transactions per month, software typically saves you enough time to justify the cost.

3. Record expenses as they occur

Log each expense immediately rather than waiting until month-end. This prevents forgotten purchases and keeps records accurate. A $50 lunch meeting is easy to forget 3 weeks later, but takes 30 seconds to log on the spot.

4. Categorize each expense

Assign every cost to a category like office supplies, travel, or marketing. Consistent categorizing makes reporting and tax preparation easier. For example, labeling a $1,200 annual software subscription under "office supplies" instead of "software" makes year-over-year comparisons unreliable.

5. Save receipts and documents

Keep proof of purchase for every business expense. Digital copies work just as well as paper for most tax purposes. The IRS requires documentation for any deduction, so a missing receipt on a $3,000 equipment purchase could cost you $660 in lost deductions at a 22% tax bracket.

6. Reconcile regularly with bank statements

Compare your expense records against bank statements weekly or monthly to catch errors and missing transactions. Even a $15 subscription you forgot to cancel adds up to $180 per year.

7. Review and analyze monthly

Look at your expense reports each month to spot trends, identify overspending, and find opportunities to cut costs. If your marketing spend jumped 40% without a matching increase in revenue, that's a signal to investigate.

How to organize and store receipts

Documenting receipts proves your expenses are legitimate if the IRS ever asks. Here's how to keep them organized.

Digital vs. physical storage

Digital storage is now the standard for most businesses. It offers searchable records, automatic backup, and access from anywhere with no physical clutter. Physical storage takes up space, can fade or get lost, and is harder to organize. The IRS accepts electronic copies as long as they're legible and include all original information, making digital the clear choice.

Best practices for receipt management

Good receipt habits save you time and protect your deductions. Follow these practices to stay organized.

• Digitize immediately: snap a photo or scan receipts the same day you receive them
• Use consistent naming: include the date, vendor, and amount in each file name
• Back up to the cloud: store copies in a secure cloud service to prevent data loss
• Match receipts to transactions: link each receipt to the corresponding expense entry in your records

Expense tracking software like Xero lets you capture receipts with your phone and automatically matches them to bank transactions, saving time and reducing manual work.

How to reimburse expenses

Reimbursing expenses means paying back someone who spent their own money on business costs. This commonly happens when owners, family members, or employees make purchases before getting company funds.

To properly reimburse someone, follow 3 steps:

1. Repay the individual: transfer the exact amount they spent back to their personal account.
2. Record the expense: enter the cost into your business books under the correct category.
3. Save the documents: keep the receipt as proof of purchase for tax purposes.

A simple reporting process ensures claims come in promptly so you can reimburse accurately and on time.

Creating expense reports

Expense reports document what was purchased, who made the purchase, and why it was necessary for the business. A complete report includes these details:

• Date of purchase: when the expense occurred
• Vendor name: where the purchase was made
• Amount: how much was spent
• Category: what type of expense it is
• Business purpose: why the purchase was necessary
• Receipt: proof of the transaction

For occasional claims, a simple spreadsheet template works well. If your team submits expenses regularly, consider an app that lets them photograph receipts and submit claims from their phone.

How to track project expenses

Tracking expenses at the project level shows you whether individual jobs, clients, or product lines are actually profitable. Without this breakdown, you might discover that your busiest projects are also your least profitable ones.

Here's how to set up project-level expense tracking:

1. Create a project or job code for each client engagement, product launch, or internal initiative. Assign a unique identifier so every cost can be tagged.
2. Tag every expense to the right project when you record it. For example, if you spend $500 on materials for Client A and $300 on travel for Client B, each cost goes to its respective project rather than a general category.
3. Track time alongside expenses. Labor is often the largest project cost. Recording hours per project lets you calculate the full cost of delivery, not just the out-of-pocket spend.
4. Review project profitability monthly. Compare total project revenue against tagged expenses and labor costs. If a project is generating $10,000 in revenue but costing $9,500 to deliver, you know your margins need attention.

Xero's tracking categories let you assign expenses to specific projects, departments, or cost centers. This gives you a clear view of where your money goes across different parts of your business without creating separate accounts for each one.

Choosing expense management software

The right expense management software saves you hours each week and reduces the risk of errors in your financial records. Choosing the best fit depends on your specific business needs.

Look for these features when evaluating your options:

• Bank feed integration: the software should connect directly to your business bank accounts and credit cards so transactions flow in automatically
• Receipt capture: a mobile app that lets you photograph receipts on the go and match them to transactions eliminates paper filing
• Expense categorization: automatic rules that sort costs into the right categories save time and keep your records consistent
• Reporting and insights: built-in reports that show spending by category, time period, or project help you make informed decisions
• Scalability: choose software that grows with your business, handling more transactions, users, and integrations as you expand
• Ease of use: your team needs to adopt the tool for it to work; a clean interface and short learning curve matter more than advanced features you won't use

Start by listing the 3 to 5 problems you most want to solve, such as lost receipts, slow reconciliation, or poor visibility into spending. Then compare how each option addresses those specific pain points rather than choosing based on feature count alone.

Common expense tracking mistakes to avoid

Even small tracking errors can lead to missed deductions or compliance issues. Watch out for these common pitfalls. For example, a missed deduction on a $5,000 equipment purchase could cost you $1,100 in unnecessary taxes at a 22% bracket.

• Mixing personal and business expenses: using 1 account for both makes it harder to track costs and raises red flags during audits
• Waiting too long to record expenses: delaying entry leads to forgotten purchases and inaccurate records
• Losing receipts: keeping documentation on file ensures you can support every deduction if the IRS asks
• Using inconsistent categories: changing how you categorize expenses makes reports unreliable and trends hard to spot
• Skipping bank reconciliation: failing to compare records against statements lets errors slip through
• Ignoring small expenses: minor costs add up and are just as deductible as large ones

Build habits that prevent these mistakes from the start, and you'll save time and money later.

FAQs on tracking business expenses

Here are answers to common questions about tracking business expenses.

What's the best way to track business expenses?

If you're processing more than a handful of transactions each week, it's a sign you've outgrown manual methods. Look for 3 red flags: you're spending more than an hour a week on data entry, you've missed a deduction in the past year, or your records don't match your bank statements. Any of these means it's time to move to dedicated software.

How do small businesses keep track of receipts?

The IRS accepts digital copies of receipts as long as they're legible and complete. Save receipt images in common formats like PDF or JPEG, and keep them for at least 3 years from your filing date. If you lose a physical receipt, contact the vendor for a duplicate or use your bank statement as supporting documentation.

Can you write off 100% of business expenses?

It depends on the category. If you buy equipment, you may be able to deduct the full cost in the year of purchase using a Section 179 election, up to $1,250,000 for 2026. For mixed-use assets like a vehicle used for both personal and business purposes, only the business-use percentage qualifies. A tax professional can help you identify which deductions apply to your situation.

How long should I keep business expense records?

The IRS recommends keeping most expense records for at least 3 years from the date you file your tax return. You should keep all records of employment taxes for at least 4 years. Also keep records for 7 years if you claim a loss from bad debt or worthless securities.

What's the difference between expense tracking and bookkeeping?

Expense tracking focuses specifically on recording and categorizing business costs. Bookkeeping is broader and includes tracking all financial transactions, including income, expenses, assets, and liabilities. Expense tracking is 1 part of the overall bookkeeping process.

What are accrued expenses?

Accrued expenses are costs your business has incurred but hasn't paid yet. Common examples include employee wages earned but not yet paid, taxes that have accumulated but aren't due until the next quarter, and utility bills that cover a period extending beyond your billing cycle. Tracking accrued expenses gives you a more accurate picture of your true financial obligations at any given time.
